However, I just don't see how Tivo could patent their dvr. It's essentially a time shifting device just like the VCR.

I think their patent is for a specific implementation, in this case, digital time-shifting. I don't care much for patents in general, but the law is such and I don't quite understand the whole point.
As for what the court thinks, we will see (how long it would take I have no idea) with the result of the Echostar / TiVo case. If TiVo loses, then that's that. If TiVo wins, they can go after others, I guess.
